[0002] In the maintenance and restoration of historical buildings, the treatment of the exterior walls is a crucial step. These buildings not only carry rich historical and cultural value, but the integrity and aesthetics of their appearance are also important criteria for measuring the success of the restoration work. However, the exterior walls of historical buildings often face a variety of challenges, such as weathering, pollution, cracks, and even partial damage, all of which require meticulous spraying operations for repair and protection.
[0003] The exterior walls of historical buildings often possess unique architectural styles and artistic value, such as carvings, reliefs, and lines. These elements require meticulous treatment during the spraying process. Traditional exterior wall spraying operations mainly rely on manual operation. Workers need to hold spray guns and spray based on visual observation and experience. While this method can meet basic restoration needs to a certain extent, it has many shortcomings in actual operation. The precision of manual spraying is limited, making it difficult to ensure that the paint is accurately sprayed in the designated location. When dealing with complex patterns or fine details, paint often overflows or is not fully covered, affecting the final restoration effect. Utility Model Content

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0028] like Figure 1-3 As shown, a spraying device for exterior wall repair construction includes a mounting rod 1. A motor 3 is fixedly mounted at one end of the mounting rod 1. The motor 3 is connected to a lead screw 4. The lead screw 4 is connected to a height adjustment assembly 6. The height adjustment assembly 6 includes a movable rod 602. One end of the movable rod 602 is rotatably connected to a slider 1, which is threadedly connected to the lead screw 4. The movable rod 602 is rotatably connected to a movable rod 601. One end of the movable rod 601 is rotatably connected to the mounting rod 1, and the other end of the movable rod 601 is rotatably connected to a slider 2. The slider 2 is slidably connected to a guide rod 603, which is positioned on the mounting rod 602. On one side of the bottom surface of the mounting rod 7, the other side of the bottom surface of the mounting rod 7 is rotatably connected to the other end of the movable rod 602. One end of the mounting rod 7 is fixed with a motor 9. The motor 9 is connected to a lead screw 10. The lead screw 10 is connected to a clamping assembly 12. The clamping assembly 12 includes a clamping plate 1202. The top surface of the clamping plate 1202 is connected to a clamping plate 1201 by bolts. The clamping plate 1201 and the clamping plate 1202 clamp a limiting laser pen 14 and a nozzle 15. One side of the top surface of the clamping plate 1201 is connected to a clamping plate 3 1203 by bolts. The clamping plate 1201 and the clamping plate 2 1202 clamp a limiting laser pen 13.
[0029] The laser pointer 13 is directed perpendicular to the bottom surface, while the laser pointer 14 is directed parallel to the bottom surface. The light beams emitted by the laser pointers 13 and 14 intersect at a point on the same horizontal line as the nozzle of the spray head 15. This intersection point allows for precise positioning of the areas on the exterior wall that require spraying and repair, ensuring that the paint sprayed from the spray head 15 is accurately applied to the areas that need repair.
[0030] The outer side of the lead screw 10 is fitted with a slider 16 and threadedly connected to it. One side of the slider 16 is slidably connected to the guide rod 11. The two ends of the guide rod 11 are respectively connected to the limiting plates fixed at both ends of the top surface of the mounting rod 7. The guide rod 11 can increase the stability of the slider 16 when it slides on the top surface of the mounting rod 7.
[0031] Limit switches 5 are provided at the top of the mounting rod 1 corresponding to the two ends of the lead screw 4. One end of the movable rod 602 presses the limit switch 5 to limit the movement range of the height adjustment component 6 and prevent excessive movement from damaging the equipment.
[0032] The mounting plates 2 fixed on both ends of the mounting rod 1 are connected to casters at their bottom ends; the casters allow the device to be moved.
[0033] Handles are fixed to both sides of the other end of the second mounting rod 7, and a controller 8 is fixed to the other end of the second mounting rod 7. The controller 8 includes a microcontroller, a relay, and a control switch. The controller 8 is electrically connected to the first motor 3, the second motor 9, and the limit switch 5.
[0034] The working principle and usage process of this utility model are as follows: When using this device, the operator can push it by holding the handle. The casters rotate, moving the device to the designated position. Then, the nozzle 15 is connected to the pumping pipeline. The controller 8 activates laser pointer one 13 and laser pointer two 14. The beams emitted by laser pointer one 13 and laser pointer two 14 intersect, and the intersection point is on the same horizontal line as the nozzle direction of nozzle 15. The intersecting point of laser pointer one 13 and laser pointer two 14 will be projected onto the exterior wall. The height is adjusted according to the location of the exterior wall requiring repair. The positions of the height adjustment component 6 and the clamping component 12 are adjusted. The controller 8 drives the motor 3 to rotate the lead screw 4, which in turn drives the slider 1 to slide along the outside of the lead screw 4. The sliding slider 1 can adjust the height of the mounting rod 7 through the movable rod 601 and the movable rod 602. After adjusting to the height of the repair position, the drive motor 9 drives the lead screw 10 to drive the slider 16, which is threaded to it, to slide horizontally on the top surface of the mounting rod 7. This allows the irradiation point to be accurately moved to the designated position, so that the repair spraying of the exterior wall can begin.
